Using Lynis : Basics
To run Lynis you should meet a few requirements:
- You have to be root (log in as normal user, su to root)
or have equivalent rights (for example by using sudo).
- Have write access to /var/log (for using a log/debug and report file)
- Have write access to /tmp (temporary files)

Depending on the installation or the path you run Lynis from, you can start it with 'lynis' (if installed and the file is available in your binary path) or 'sh lynis' or './lynis'.
